Howto Postfix block multiple senders in one "mail from:"
 
Hello palls,
Obviously this is new mass spam wave and I'm concerned a lot of this bad effect.
But with my knowledge can't achieve effective protection :(
Could some one help me?

The usual message coming from my real users, ofcourse outside of my domain for exmlp:
Mail from: <user1@mydomain.com>,<user2@mydomain.com>,<user_1@ mydomain.com>,<user-1@mydomain.com>,<user_2@mydomain.com>,<user-2@mydomain.com>
Some of them are legitimate but message can't be send from many users, right ?

Could someone advanced with Postfix MTA to advice me what can I do about that!

Thanks in advance

Thanks for the suggestion but not helpful. Although here is not total noob.
But the problem with multiple "mail from:" spam continues with full speed ahead (over my head) :(
